Calculate the LCM of 640,583,749,158

Given numbers are 640,583,749,158

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 640,583,749,158 is 22077883520.

Find LCM of 640,583,749,158 with Prime Factorization


2 640, 583, 749, 158
320, 583, 749, 79

Multiply the prime numbers at the bottom and the left side.

2 x 320 x 583 x 749 x 79 = 22077883520

Therefore, the lowest common multiple of 640,583,749,158 is 22077883520.

LCM Formula to Find Lowest Common Multiple of 640,583,749,158

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

640 x 583 x 749 x 158 = 44155767040

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

583 : 1, 11, 53, 583

749 : 1, 7, 107, 749

158 : 1, 2, 79, 158

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,583,749,158, is 1.

Now, the common factors can be found like this.

640:2x 2x 2x 2x 2x 2x 2x 5

583:11x 53

749:7x 107

158:2x 79

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2 = 2

Therefore, the value for common factors is 2.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 44155767040/(1x2)

LCM = 44155767040/2

LCM = 22077883520

Thus, we can understand that the LCM of 640,583,749,158 is 22077883520.
